I've been offered recently an used Specialized Srm, donno the exact year but has same stickers as the one used by Astana in 2010 (see below photo).

I wanted to know if early model of Specialized Srm use the same specs as the Lightning cranks, which would meant I could use it also on a BSA frame.By looking at info in here, it seems that Specialized and Lightning cranksets were similar till 2011, but from 2012 the big S changed design.

NO! been there done that, specialized spindle is OSBB length which is about 20mm (i forget the exact figure) too short. You can bodge it with a lightning crank on the spider, but the spider is offset away from the frame too far, and is rotated about 18degrees, meaning that one chainring bolt is partially obscured by the crank arm. Don't do it unless you have a proper BB30 native frame.
